QUESTION 42
In an MPLS VPN environment, the QoS making over the MPLS backbone must be different from the one that is received from the customer. The forwarding on the egress PE is based on the marking that is set by the ingress PE. Which null label and QoS mode can achieve this?

A. BGP should not advertise a route until that route has been learned via an IGP.
B. Routing information received through an EBGP session is not forwarding to another EBGP neighbor, only to IBGP neighbors.
C. BGP neighbor peering are established and synchronized using TCP.
D. BGP should not advertise a route when that route has been learned via an IGP.
E. Routing information received through an IBGP session is not forwarding to another IBGP neighbor, only to EBGP neighbors.

Answer: A

QUESTION 47
Refer to the exhibit. R2 and R3 cannot install IS-IS IPv6 routes. What is the root cause?

A. R2 is missing the metric-style wide command under the IS-IS process.
B. R3 is missing the multi-topology transition command under the IS-IS address-family IPv6 process.
C. R2 is missing the multi-topology command under the IS-IS address-family IPv6 process.
D. R3 is missing the metric-style wide command under the IS-IS process.

Answer: B

QUESTION 48
Which statement about Software Maintenance Upgrade is true?

A. CRS-1 SMU can be applied to a different platform, and vice versa.
B. SMU is an executable code for running a process or libraries that are shared between the different processes.
C. SMUs for each release are individually downloadable from Cisco.com and come in the form of a tar ball.
D. SMUs provide software fixes for critical network down and qualification blocking issues. Therefore, every software defect has a corresponding SMU.
E. SMUs are release-specific. If an issue affects multiple platforms or releases, an SMU is built separately for each release and each platform.

Answer: E
Explanation:
SMUs for each release are individually downloadable from Cisco.com, whereas the bootable files and optional PIEs come in the form of a tarball. SMUs are release specific. If an issue affects multiple platforms or releases, an SMU will be separately built for each release and each platform depending on the mission-critical need.
A CRS-1 SMU cannot be applied to a different platform, and vice versa. SMUs provide software fixes for critical network-down and qualification-blocking issues. Therefore, every software defect will not have a corresponding SMU.

A. TE tunnels that are configured with the FRR option cannot be used as backup tunnels.
B. TE tunnels that are configured with the FRR option can be used as backup tunnels.
C. The backup tunnel that is used to protect a physical interface must have a valid IP address configured.
D. Interfaces must use MPLS global label allocation.
E. The source IP address of use backup tunnel and the merge point (MP) should not be reachable.

Answer: ACD

QUESTION 50
Refer to the exhibit. Two MPLS TE tunnels are configured with a total bandwidth guarantee of 100 Mbps. However, Tunnel 1 has a requirement to have one-fifth of this total bandwidth. Which two configurations accomplish this goal? (Choose two.)
